How to Determine If You Need to Bring You Car to an Auto Repair Shop

The check engine light is one of the most confusing and frustrating facets of owning a car. As most of you already know, the check engine light is nothing more than a light that illuminates on the dashboard when there is a problem. However, the light itself gives no information whatsoever about the source of the problem. All you know is that there is something wrong with your vehicle. So, if you want to find out what the issue is, you may need to bring your car to an auto repair shop. Luckily, there are a few thing you can do on your own that may help you identify the issue and fix it yourself. This can help you save a lot of money.

The oxygen sensor
One of the most common reasons why a check engine light comes on is a malfunctioning oxygen sensor. An oxygen sensor is a device that monitors the unburned oxygen from the exhaust. Once it does the measurements, this sensor sends the information to the board computer which will adjust the air and gas mix that gets injected into the engine. In other words, the oxygen sensor is directly responsible with your car’s fuel consumption. If the sensor is malfunctioning, the car will consume more fuel than usual, generate a lot of smoke, and present issues when driving.

The gas cap
You wouldn’t believe that a broken gas cap can cause your check engine light to come on, but it does. A broken or cracked gas cap can cause fuel vapors to leak out, causing the whole fuel system to develop problems. Most cars are equipped with sensors that verify whether your gas cap is in good condition or not. If any problem is found, these sensors will alert your board computer which will make the check engine light come “on”. The good news is that replacing the broken gas cap will fix the problem immediately.

These are only two of the most common culprits for a check engine light. Unfortunately, there are many more problems that can cause your engine light to illuminate. However, to fix these problems, you need to bring your car to an auto repair shop. We strongly suggest you visit DeVoss Auto Service LLC in Richmond, VA.
